The cliff behind Nurwanto is high and contains high-quality sand.

The part of the cliff wall that the miners are digging is dense sand and to get the sand they have to dig little by little so that the collected sand will not be fast, it will take quite a long time to fill one truck load, but the top of the cliff is loose sand and Nurwanto to speed up the results of the sand pile immediately slides the cliff from the top of the cliff from there Nurwanto is able to slide the cliff and drop the rocks that are on the cliff and if one day we reach the cliff behind the high one, the condition of the cliff will definitely be much higher and can be fast when getting quality sand #merapi slope #sand cliff #diverting cliff #slide cliff
